VNC (Virtual Network Computing) ndi teknoloji ya kugawidwa kwa madera akutali , mawonekedwe a kutalika kwa makompyuta . VNC imathandiza mawonedwe owonetserako mafoni a kompyuta imodzi kuti iwonedwe ndi kuyendetsedwa pa intaneti.
Mapulogalamu apamwamba a pakompyuta monga VNC ndi othandiza pa makompyuta apakompyuta , kulola munthu kuti afotokoze mapepala awo kuchokera kumbali ina ya nyumba kapena akuyenda. Zimathandizanso kwa ogwira ntchito pa intaneti m'makampani, monga Dipatimenti ya Information Technology (IT) yomwe ikufunikira kuyendetsa mavuto awo ogwira ntchito.
Mapulogalamu a VNC
VNC inakhazikitsidwa ngati polojekiti yowonetsera poyera kumapeto kwa zaka za m'ma 1990. Zida zambiri zapansi pa kompyuta zomwe zakhazikitsidwa pa VNC zinakhazikitsidwa. Gulu loyamba la VNC chitukuko linapanga phukusi lotchedwa RealVNC . Zina zowonjezera zotchuka zimaphatikizapo UltraVNC ndi TightVNC . VNC imathandizira machitidwe onse amakono omwe akuphatikizapo Mawindo, MacOS, ndi Linux. Kuti mudziwe zambiri, onani VNC Free Software Downloads .
Momwe VNC Works
VNC imagwira ntchito mwa kasitomala / chithunzi cha seva ndikugwiritsira ntchito pulojekiti yapadera yotchedwa Remote Frame Buffer (RFB). VNC makasitomala (omwe nthawi zina amatchedwa oyang'ana) amagawana nawo othandizira (kugwiritsira ntchito makina osakaniza, kuphatikizapo kusuntha kwa phokoso ndi kuwongolera kapena kukhudza makina) ndi seva. MaSeva a VNC amatha kuwona zomwe zili mkatimo ndikuwatsananso kwa kasitomala.
Malumikizano pa RFB mwachizolowezi amapita ku TCP port 5900 pa seva.
Njira Zina Zopangira VNC
Ntchito za VNC, komabe, kawirikawiri, zimawoneka ngati zocheperapo ndipo zimapereka zochepa zochepa ndi zosankha zotetezera kusiyana ndi njira zatsopano.
Microsoft imaphatikizapo machitidwe apakompyuta akutali m'ntchito yake yoyambira kuyambira Windows XP. Mawindo Operekera Mawindo a Windows (WRD) amathandiza PC kulandirira mapulogalamu apakati pazilumikizi. Kuphatikiza pa chithandizo cha makasitomala opangidwa ndi zipangizo zina za Windows, Apple iOS ndi Android piritsi ndi mafoni yamakono angagwirenso ntchito monga makasitomala a kutalika kwa Windows (koma osati ma seva) kudzera pa mapulogalamu omwe alipo.
Mosiyana ndi VNC yomwe imagwiritsa ntchito RFB protocol, WRD imagwiritsa ntchito Remote Desktop Protocol (RDP). RDP siigwira ntchito mwachindunji ndi omangirira ngati RFB. M'malo mwake, RDP imaphwanya mawonekedwe a desktop kukhala malemba otsogolera ojambula zithunzi ndi kutumiza malangizo okhawo kudera lakutali. Kusiyanitsa kwa ndondomeko kumayambitsa magawo a WRD pogwiritsa ntchito njira zochepa zogwiritsira ntchito makanema komanso kukhala omvera kwambiri pazomwe amagwiritsa ntchito kuposa machitidwe a VNC. Komabe, zimatanthauzanso kuti makasitomala a WRD sangathe kuwonetsa mawonedwe enieni a chipangizo chakutali koma m'malo mwake ayenera kugwira ntchito ndi gawo lawo lokhalokha.
Google inakhazikitsa malo osungirako kutalika kwa Chrome komanso puloteni yake ya Chromoting yothandizira zipangizo za Chrome OS zofanana ndi Windows Remote Desktop. Apple yatambasulira protocol ya RFB ndi zowonjezera chitetezo ndi zowonjezera zomwe zimapangidwira kukhazikitsa njira yake ya Apple Remote Desktop (ARD) kwa ma MacOS. Pulogalamu ya dzina lomwelo imapangitsa zipangizo za iOS kugwira ntchito monga makasitomala akutali. Mapulogalamu ena ambiri apakati pazipangizo zakutali apangidwa ndi odzigulitsa okha mapulogalamu.
